In the present experimental investigation, performance, emission and combustion characteristics of a single cylinder diesel engine using diesel-biodiesel blends and antioxidant containing biodiesel test fuels was carried out. The potential suitability of aromatic amine based antioxidants to enhance the oxidation stability of biodiesel on one hand and reduction of tail pipe oxides of nitrogen (NOx) on the other were evaluated. Tertiary Butyl Hydroquinone (TBHQ) was considered as the antioxidant and Calophyllum Inophyllum vegetable oil was taken as the feedstock for biodiesel production. The test fuel samples were neat diesel (D100), 10% and 20% blend of Calophyllum biodiesel with diesel (CB10 and CB20) and 1500 ppm of TBHQ in CB10 and CB20 (CBT10 and CBT20). The results indicated that neat biodiesel blended test fuels (CB10 and CB20) exhibited lower brake thermal efficiency compared to the diesel baseline by a margin of 3% to 10% at full load.
